用户帐户无权访问App Annie Intelligence API

Question

当我尝试使用以下App Annie Intelligence API

https://api.appannie.com/v1.3/intelligence/apps/ios/market_size?data_break_down=country&categories=Overall&device=iphone&granularity=monthly&start_date=2018-01-01

我遇到了403 forbidden错误。

{
    "code": 403,
    "error": "This user account does not have access to App Annie Intelligence API."
}

我可以知道如何启用App Annie Intelligence API的访问权限
